Hyundai - Santafe :: 2013 - Sudden Power Loss When Accelerating From A Slow Speed Coast

Occasionally, randomly, and unpredictably when accelerating from a slow speed coast I get no power response when I press down on the accelerator. It's as if the engine has stalled, but it has not. When the accelerator is held down for a few seconds (maybe 3 to 7) power comes back with a rush. Examples:

1. Making a U turn from a left turn late. Accelerate slowly forward, take foot off gas as the turn is initiated, press down on gas to accelerate out of the turn and get no immediate power response.

2. Making a left turn into a suicide lane. Accelerate to cross 2 traffic lanes, let off gas and coast slowly forward in the suicide lane while waiting for oncoming traffic to clear, traffic clears, press down on gas and get to response. Continue to press slowly down--no response. Hold the accelerator half or 3/4 down, power surges back after a few seconds.

3. Rolling slowly down a long left turn lane with foot off gas timing oncoming traffic, traffic clears, press down on gas to initiate the turn, no response. Let up on gas and press down again, no response, let up an press down again and car reacts normally.

Occurrences of this problem have been very random. I have spent a good deal of time in vacant parking lots trying to cause the problem to occur without any luck even though I know well the conditions under which it happens. I have left the car with the dealer but, of course, they can't observe the problem either. I have driven nearly 1000 miles without an incident and then had 2 occurrences within 4 miles of each other. I have about 5000 miles on the car and have logged 17 incidents.

Loosing power in traffic is, of course, dangerous. I was about to initiate action under California's Lemon Law when I went to England for 3 weeks in Sept. I rented an Audi A1 and to my surprise I experienced a very similar problem, but it happened much more often. An example would be entering a roundabout, letting up on the accelerator while looking at directional signs, reapplying accelerator pressure and getting no response. Unlike the Hyundai I didn't seem to lose all power, but couldn't get any acceleration. The Hyundai engine is the 4 cylinder turbo and has an electronic throttle. I don't know what the Audi had by way of mechanics. I'm at a complete loss; is there something I don't understand about electronic throttles? I don't have a clue about the source of this problem, but I know I need to get it resolved before I get rear ended.

Hyundai - Santafe :: Brake Pedal Making Audible Click When Press Down On It

I have a 2002 Hyundai Santa Fe with 152,000 miles on it. Last night, when I got in my car after work, I noticed that the brake pedal is now making an audible click when I press down on it. This has never occurred before (including on my way to work yesterday), but is still doing it today.

No lights are present on the dashboard, and I have not noticed any difference in the performance of my brakes. What could cause this, and should I be concerned?

Toyota - Yaris :: 2010 - Unintentional Sudden Deceleration

I have a 2010 Toyota Yaris at 33,000 miles . I love the car BUT on two occasions, the following has happened:

I am driving at 70 mph on the highway. Out of nowhere the car starts decelerating. I watch the needle on the mileage gauge fall and try to accelerate but even when the gas pedal to the floor, nothing happens. No odd noises, no lights go on on the dashboard. Fortunately, I am able to get over on the side of the highway safely. As I brake however, the car kind of lurches forward and feels like it wants to accelerate. After I pump the brakes briefly, the lurching stops and I start driving again and it is like nothing happened. At no time did I turn the car off.

Elantra MD (2010-15) :: 2016 - Rapid Deceleration Or Sometimes Sudden Acceleration And Moves Unevenly

When driving, if I let off on the gas, my 2016 Elantra kinda coasts for a second or 2 and then does a rapid deceleration or sometimes sudden acceleration and moves unevenly instead of coming to a smooth stop or slowly coasting at a constant speed. The car jerks just enough to feel like I'm braking a bit. Not smooth like it should be.

I have been using my Elantra 2016 since end of last year. It has mostly been like this since the last few months and lately it has increased. Also, lately my fuel economy hasn't been great as well. Why my Elantra has been behaving like this?

Sonata I45 (YF - 2011+) :: Sudden Unintended Acceleration

The owner of the car claims that there was sudden unintended acceleration, and it was 09' Sonata.

Video .....

I thought this should be very concerned to us, since we all drive 11' sonata & up. I heard Hyundai installs some kinds of system to prevent this incident to all cars manufactured after May of 2012.

Hyundai - Santafe :: 2010 - Humming Noise Comes Out Of Front Passenger Side Under Dashboard

We have a 2010 Hyundai Santa Fe. Over the last year, there has been a humming noise that comes out of the front passenger side under the dashboard. This humming noise starts when the car is in motion (above say 5mph) and then lasts presumably at highway speeds but the road noise sort of block it out. When we come to a stop, the humming noise persists about 5 seconds after we come to a complete stop and then goes away. I checked the tire and it's not rubbing anything and tire pressures are even. We had the tires rotated but the noise still comes from the front passenger side. We had a wheel alignment and the noise still persists. There are no issues with steering or braking.

I think it's probably related to the strut or suspension system? Is there a pump in the area? It's been a year and we've sort of gotten used to the noise, and nothing's broken.

Hyundai - Sonata :: 2010 - Lunging Forward And Stopping With Sudden Thump When Press Down Brakes

My parents have a 2010 Hyundai Sonata. About a month ago my mom noticed that when she starts to brake, the car stops fine but then it stops again almost, with a loud thunk. The best way to describe it is that you press down the brake, the car stops, then a few seconds later the car feels like it is lunging forward and stopping again with a sudden thump. (Although I don't think it really actually moves at all).

Hyundai - Santafe :: ABS / ESC Lights With Brakes?

While driving, the ABS light came on, with what felt like the brakes. That stopped, now the ESC light comes on (or blinks), still with the brakes, or something acting against the wheels. This can happen at any speed and only happens from once a week to once every few weeks. What is going on?

Hyundai - Santafe :: Hesitation On Acceleration And Rpm Changes While Cruising

I have a 04 santa fe 2.4L 4cyl. I recently did an engine swap, old motor threw a connecting rod. I put my intake, exhaust manifold and head on it. Timed it. All new gaskets. Turn the key and it fires right up and runs great. But when you accelerate it sounds loud (almost diesel like) and doesn't shift at the right time, also while trying to cruise it will drop about 300 rpms and then come back up, then back down and up every 3 to 5 seconds. The transmission was fine when the old motor came out. The head/intake were fine also. All the vacuum lines are connected, cant hear a vacuum leak anywhere. But it keeps throwing a throttle body sensor code and it wasn't broken when the old motor went, i even swapped another used one on it and it still throws that code. I am thinking it has to be intake related.

Hyundai - Santafe :: 2004 - Won't Start After Fueling

My 2004 Santa Fe doesn't want to start after fueling. It doesn't matter whether it was just a few dollars worth or a full fill up. After pumping the gas and recapping securely, I have to press and hold the Accelerator to get it to catch. I had the purge control valve replaced a few months ago. And my car started mourn normally for a while. However I'm back to having to push progressively harder on the gas pedal to get it to start after gassing up.

Hyundai - Santafe :: 2003 Won't Start After Filling With Gas

I have a 2003 hyundai Santa Fe that has had a problem for a few years that I can not figure out, nor can the hyundai dealership. (Though they seem to only want to hook it up to a computer, which tells them that nothing is wrong.) After filling up the car with gas, the car will turn over, but will stall immediately. You can press on the gas and it will stay going, but once you take your foot off the gas it stalls. It act like when you used to flood the corroborator. It takes about 4 times of turning over the car and stalling before it runs normally.

It is a GLS 4-cyl automatic AWD.

Hyundai - Santafe :: 1995 Try To Turn Over But Won't Start

My (mom's) Hundai will not start. It tries to turn over but never makes it. We don't smell gas, not flooded, might be the fuel pump. The code sensor device will not give a code to indicate a specific problem.

In the past, the car will give a static shock every time you get out and push door closed. Very difficult to start and gas must be pumped to start after gassing up. Also, a bell (ding sound) rings at random even if the car is driving. What to look at next?

Hyundai - Santafe :: 2005 Won't Start After Filling With Gas?

I have a 2005 Hyundai Santa Fe, about 128,000 miles on it. For the past 5 months or so, the engine simply won't start after filling with gas - and only after filling with gas. I've tried filling partially from near-empty, as well as filling full from halfway or more full...it consistently won't start up after filling with gas.

After turning the ignition, the engine will turn over, but quickly quits. Lately it's had more trouble turning over at all. To get the car moving, I need to actually feed it gas with the pedal, and "simulate" idle. Even after a couple of minutes, if I let off the pedal it dies right away....as if gas just isn't getting to the engine on its own.

In order to get the car moving, I just have to keep feeding it a bit of gas while shifting to drive (and stepping on the brake), then I give more gas and let the brake go almost as if it's manual-transmission....off it goes.

Oddest thing: as soon as that happens; as soon as the car moves forward (even just to get out of the gas station), everything's back to normal. The car idles healthily at the next stop, as if nothing happened.

No check-engine light, no diagnostic codes come up with a scan. Same results on warm or cold days. Most recent maintenance on it was new spark plugs almost a year ago (doesn't seem related).

Of course, the only time it DID fire up normally after filling with gas was when I had the mechanic with me in the car!

Hyundai - Santafe :: RPMs Going Low And Stalling Out While Driving

I have a 2004 Hyundai Santa Fe with about 83,000 miles. Lately it has been having issue with the rpm's going low and stalling out while I'm driving. I've taken it to a mechanic and it has not been resolved. He said it does not need a tune up and it's nothing with my fuel. I've also heard it could be a crank shaft censor but he says no. The check engine light has come on sometimes, very quickly but then goes off.. He ran the code but nothing came up. So then what's causing my car to do this?? While the car is running and I'm in park, the rpm's will go from 2 to almost 0 then back up again. While I'm driving down the road it does the same thing and sometimes it completely stalls out while I'm going about 40mph. So incredibly scary. What this could be so I can take it back and get it fixed!!!! I'm so scared to drive it but I have to get to work.

Hyundai - SantaFe :: 2003 - Sputtering As Soon As Fill Up

About a year ago, I tried to top off the tank of my 2003 Hyundai Santa Fe. Since that time, the car has been sputtering as soon as a fill up. It doesn't sputter at other times. I have heard that I may have damaged my evaporation system. I have taken it to quite a few mechanics who tried to work on the evap system, but they could not solve the problem. Is there a simple and easy way to fix this??

Hyundai - Santafe :: Passenger Seat Cannot Be Moved Up And Down

the passenger seat in our 2015 hyundai santa fe sport is not power but the seat can manually adjust forward and backward and the back rest can be moved backward and forward. The seat cannot be moved up and down. It is way too low and it feels like sitting in a "pit". The dealer said to sit on a pillow but when I sit on a pillow the air bag light will not go off (so the passenger air bag is not activated). If I sit on a book, the air bag light does go off but who wants to sit on a hard book all the time. The air bag warning light does go off when I sit on the seat itself.
